Hello
I am new to this forum and am a long time CM user which I am using on my phone at the moment. However, having discovered the aggressive thermal throttling on this phone (CPU-intensive tasks seem to throttle the max CPU speed down to 1190 MHz very very quickly, before the phone even gets warm), I'm trying to find a custom kernel that will work with CM. I don't care about any fancy features such as S2W or DT2W and if the kernel allows these to be disabled then that would be even better. Basically looking for a reliable, stable kernel that can be configured to be as close to stock as possible, but which would stop the aggressive thermal throttling.
Thanks
Hi, and Welcome!
I'm afraid that your post likely will be considered a "Best ROM or kernel" thread which is not allowed. It's usually suggested that you go over to the development forum and try out kernels for yourself because everybody's needs are different, and so on.

Only Chaos kernel is compatiblewith CM atm afaik because its a CAF based kernel.

I probably will do that, but I thought this might not fall in the realm of "best kernel" because I have listed some specific criteria...

I'll give that a try. From browsing earlier I noticed that n30Hammer and ElementalX have separate links for CM11, I figured they would be compatible.

Oh, believe me, I think your post is fine. I just wanted to give you a polite heads-up before the more zealous members started chiming in.

Hi,
Yes they are compatible too, for ElementalX choose the right version. Both have thermal settings.
There is also: http://forum.xda-developers.com/showthread.php?t=2649458 and http://forum.xda-developers.com/showthread.php?t=2633955 (almost the same kernels apart the Toolchain), compatible with CM/CM based rom with thermal control too.

All you do is make it "best kernel for specific criteria" then. Mods see it all as the same thing.
I'm giving ElementalX a try for now. The mods can feel free to close this thread if they see fit.
Thanks for all the replies.
before this gets locked you need a CAF kernel, Chaos kernel comes to mind, they do nice work. Comes with NXT tweaks which allows you to customize almost everything including temp.
I tried all possible CM11 kernels and Chaos kernel has in my opinion a very nice CPU load management.
Other kernels will stay for several seconds in max frequency after a power demand which result in higher CPU battery drain.
Bricked kernel was also excellent in that field and super responsive but the developer takes a break at the moment so the kernel is not usable for the CAF Version of CM after 25.01.14 without further modding and the AOSP mod for CM CAF is producing some weird behavior on my phone so I go for Chaos and CM at the moment.
I found Elemental would keep upping the minimum CPU to 1267 instead of 300, so at the moment I'm trying out NexXxt as @viking37 linked above, and using Trickster to configure the temps it seems to be working pretty good.

It's normal, it's how Mpdecision from Qualcomm works (for smoothness purpose). Each time you touch the screen the min CPU freq is increased to 1,26 Ghz. In fact the apps reads this at the min CPU freq because you touch the screen to open it. When you stop to touch the screen the min CPU freq will go back to 300 Mhz, the app needs to update the reading of the min CPU freq too but with Trickser Mod it seems it stuck at 1.26 Ghz all the time (for the reading only) but your min CPU freq is 300 Mhz when you don't touch the screen. You will see better this behavior with an app with "live reading CPU freq" like PerfMon or System Monitor.
You can use the "lock frequency" setting in Trickster Mod after set your min CPU freq to 300Mhz, if you want.

Not good option. Only locks core 0. Core 1 still affected.
Only full workaround is delete /system/lib/hw/power.msm8974.so

Hi,
Yep, right
Old thinking that is income , sorry for the mistake. I edited my post
Just thought I'd report back, been using NexXxt with custom thermal config using Trickster, and have had no problems at all, great battery life and no more throttling.

I was wondering if anyone knew what the default thermal throttle threshold for nexus 5 is.. Also how far is it safe to push?

its either 100 or 105C(I believe 105C). how safe? I've hit it hundreds of times, on purpose.

Are you sure its not in the 60s? Coz in stock my cpu benches were lower than nexus 4.once i flashed a custom kernel with 70degrees threshold my cpu bench went up there with the note 3..

ah, I misunderstood your question. I gave you the thermal shutdown temp. default is 65C, when it starts throttling.

Harder if you keep thermal throttle on, which most people do :silly:
Silly northern hemisphere, it's Winter here in Australia My CPU temp goes down to 20C without artificial cooling lol.
Just curious....I checked the CPU states of my phone using Better Battery Stats and notice that it never goes above 1.8ghz. As I understand it, the Mate 9 is 4x2.4 GHz Cortex-A73 & 4x1.8 GHz Cortex-A53. Perhaps with my usage the Mate 9 never is required to go above 1.8 but I am curious if others have seen their CPU hit 2.4?
Yup. Is better battery displaying both big and little cores?

Bugs:
With hal3 active there will be problems with the camera in third-party applications (the default is off)
The "menu" button is not configurable, is the "menu" always called? QRAttached fileFIX_FRAMEWORK.zip (9.27 MB)
There may be problems with the stock camera (if problems with other cameras do not go away) - QRAttached filemarkw-oss-cam.zip (724.45 KB)
It is possible to "stick" the notification of charging / connecting when disconnecting usb / charging (it is treated by resetting)
Setting it right now, it's surely more updated than Hrafninn's last RR rom, mostly for the new kernel with Wi-Fi updated drivers and hotplug, also with optional lowered Cpu freq at 400MHz. Customizations seems to be almost on par with RR, great!
Let's see with Greenify and some blocked alarms/wakelock, what autonomy can provide :fingers-crossed:

Also it have 2.21GHz max freq. that gives antutu over 65k and geekbench 4.500+. But that 400MHz is unusable. Kernel always switching between 652-2.21 GHz and when i tried to set minimum freq to 400MHz my device freeze and rebooted.

It depends on your specific Cpu and other variables, mine, for now seems to be stable...:fingers-crossed:
Anyway I saw there's a huge NETLINK wakelock denying the deepsleep of my device...Now I've deleted all my alarms and wakelock blocked things and from My Android Tools (maybe I was wrong on something that caused the wakelock) and it's fully charged stopped manually at 99%, let's see what happens. The wifi (maybe a little weaker than Miui) and bluetooth scanning are off. Charging was at high speed with original charger and Aukey "big" cable , Led was switched on immediately, but then I've charged with the device off, to speed up the process, and noticed that there's no percentage, only an empty animated icon. Fingerprint is ok, just few issues when trying to unlock on Nova Launcher's home page! I've found that give root to Nova instead of "administrator's privilege" is resolving this issue (Root is needed to use the "lock now button" with Nova).
I've also set the Low Cpu freq at 400MHz and limited the high at 2GHz instead of modified 2.2GHz. Today I'll test also the "equalizer" system app, that yesterday crashed when I opened up from inside Shuttle music app.
I hope to solve the wakelock problem.

Using it right now and works perfectly

Yes it's safe.It's a small overclock and beside that there are mechanisms like cpu throttling and core offline that prevent overheating.Also the rom is not fast because of that, you can barelly notice any improvement from a 10% speed increase.
What about battery? I'm on ViperOS right now because that Pixel Experience that offer, but I really want to try this one

this is the thing mate.. im not running my phone full4K all the time. i dont need that , all i need is more power out of the cpu and gpu. so OCing with the stock 1080p config wont harm ( at least thats what i assume given the fact that current temps are healthy af).
If there is anyone to guide me with this process , i would love to give this a try ( take one for the team)
